To validate the French version of the CAM, a multicenter diagnostic study will be conducted. The principle of this study is identical to the study of Inouye which initially validated the CAM in 1990. This is to verify the diagnostic properties of the CAM (French version) compared to the gold standard represented by the confused state of psychiatric diagnosis using the DSM. A representative sample of geriatric patients for whom a delirium is suspected, will be recruited in the various participating centers, patients will undergo two consecutive visits: - A visit by a geriatrician, during which the confused state of the patient will be evaluated using the French version of the CAM. - A visit by a psychiatrist during which the diagnosis of confusional state will be evaluated using the gold standard criteria of the DSM IV. These two evaluations will be conducted on the same day and blinded from each other. The order of these two procedures will be balanced within each center. This process will allow the calculation of diagnostic parameters of the CAM French version (validation competitive): sensitivity, specificity, positive and negative predictive values .
Pain, confusion, and breaks in normal sleep cycles have been challenges commonly faced by patients after undergoing joint surgeries. To address these issues, melatonin, an inexpensive over-the-counter supplement, has shown in previous to help manage sleep disorders, prevent and treat post-operative confusion in patients over 70 years of age, and reduce pain. The purpose of this study is to establish whether melatonin can aid in reducing pain and post-operative confusion and improve sleep quality after total knee replacement
Rationale: Delirium is a frequently encountered problem in ICU patients and leads to increased morbidity and mortality; Delirium in the ICU is associated with sleep deprivation which is among others caused by a disrupted circadian rhythm; Dynamic Light application aims at restoring a proper circadian rhythm by rhythmically alternating light intensity and has shown beneficial effects in sleep quality. Whether DLA improves sleep quality and reduces delirium incidence in ICU patients is not known Goals/endpoints: To evaluate the feasibility of dynamic light application in the ICU and to study the effects of dynamic light application on the incidence of delirium, duration of mechanical ventilation, the number of ICU and hospital days, and mortality in a mixed population of medical and surgical ICU patients. In a subgroup of patients with a high risk of developing delirium, markers of circadian rhythm, inflammation and brain damage and post ICU HRQoL will be assessed Study design: prospective randomized single centre trial Study population: adult ICU patients > 18 years old with an expected duration of stay of more than 24 hours Intervention: Patients will be randomized between Standard Care or Standard Care + DLA; When receiving standard care, normal lighting settings will be used in that patient room, which can be controlled by the medical personnel; In the rooms of patients randomized to the DLA group, DL is applied with a changing intensity during the day according to a fixed rhythm, which is regulated centrally. In addition when necessary, an intervention light can be used which can be operated in the patient room. Study parameters/endpoints: incidence of delirium as measured by the CAM-ICU; duration of mechanical ventilation, ICU and total hospital mortality; ICU and hospital LOS; Serum levels of inflammatory markers and markers of brain damage, urinary levels of markers of circadian rhythm, data of HRQoL questionnaires and total light exposure in both groups
This research is an evaluation of the MMHU compared to standard care. Patients who are over 65 and 'confused' at admission will be randomly allocated to the MMHU or standard care. The MMHU does not have capacity for all confused older patients admitted to NUH, and random allocation is similar to what happens in practice currently. For this study, 480 of these patients will be recruited, together with a carer (240 from the MMHU, 240 from standard care wards). The investigators will collect baseline information about the patient participant's physical and mental health and disability. The investigators will count the total days spent at home and measure patient participants' health status after 3 months, and use of resources over six months. Carer strain and quality of life will be measured at baseline and follow up.
The objective of this study is to investigate whether JNJ-40411813 versus placebo reduces psychosis-like symptoms, induced by infusion of a low dose of ketamine. Effects of JNJ-40411813 on ketamine-induced symptoms will be evaluated about 3 hours after a single oral dose when the concentration of JNJ-40411813 in the blood is at its maximum and up to 24 hours after dose administration to assess the duration of a potential JNJ-40411813 effect.
Patients with traumatic brain injury often experience a period of acute confusion that may include agitation as they recover from their injuries. While this confusion generally resolves with time, patients may pose increased risk of injury to themselves or others during this period. Their behavior may also increase stress for family members and interfere with their ability to benefit from rehabilitation therapies. A number of different medications have been used to treat confusion to decrease agitation, decrease risk of injury, and improve participation in rehabilitation therapies. To this point, there has not been a research or scientific basis for knowing which medication is the best for a specific patient. The overall goal of this study is to conduct a scientific investigation to help determine which medication works best to treat confusion. Study hypothesis: Amantadine will reduce the severity and number of symptoms of acute confusion after traumatic brain injury.
This study compared standard hospital restraints to a newer safety net restraint system to compare them for acceptability, tolerance, duration of restrain, length of stay in the hospital, and satisfaction of MD, nurse, and relatives of patients.
